_1__ *Five goes into eight one time, when you subtract that
5| 87 you get three, then drop the seven down to find the
_5_ second digit of your answer***
37
_17_ **Since 5 can't go into 2, you place a decimal point
5| 87 and add a zero to your remaining number***
_-5_
37
-35
= 02
_17.4_ ***5 goes into 20 four times***
5|87
-5
= 37
-35
= 020
**Answer is 17.4 times!!***

1 times 5 equals 5
5 times 5 equals 25
10 times 5 equals 50
so if you don't have a calculator and are a flat null in math, you can use this process...
87 - 50 = 37 and 10 fives
37 - 25 = 12 and 5 fives (total of 15 fives)
12 - 5 = 7 and 1 five (total now at 16 fives)
7 - 5 = 2 and another five (new total at 17 fives)
leaving you with 2 out of 5 (to make it into a decimal make the dominator 10, so you multiply both top and bottom by 2, so you end up with 4/10 or 0.4. Add this to your 'fives' and you have your answer...
17.4

87 / 5 = 17.4
17 + 17 + 17 + 17 + 17 = 85 + the remainder
17 * 5 = 85 + the remainder.
Ask your math teacher to explain to you how to solve multiplication by using the axiom of addition. I used to do this when I was at grade 2 (elementary school)
